When Windows Vista was launched, the Free Software Foundation started its BadVista campaign, which was aimed at informing users about what the FSF considered user-restrictive features in Vista. Luckily for the FSF, Vista didn't really need a bad-mouthing campaign to fail. Now that Windows 7 is receiving a lot of positive press, the FSF dusted off the BadVista drum, and gave it a fresh coat of paint.

Like others have pointed out, FSF is a negative raising entity, and dictatorial at best.

Anyway, nothing they can, would, will do, will make an impact on the sales or growth of Windows 7 or any other operating system in general.

Look at their support of Darwin. They renamed it GNU/Darwin after Apple open sourced darwin ( I guess Mr. humility, Stallman, has to put his two cents everywhere), and what happened, it died on the vine. Go look at the website. They can't develop nothing relevant.
Criticism is easy, getting things done is the real work!
Windows work and I can get things done without tinkering with it. When I want to tinker, I go to my garage and work on my old car!
